PUMP.

SPECIFICATION forming part of Letters Patent No. 486,350, dated November15, 1892. Application filed December 3. 1889. Serial No. 332.452. (Nomodel.)

To all whom t may concern:

Be it known that I, PHILIP A. MYERS, of Ashland, in the county ofAshland and State of Ohio, have invented a new and useful Improvement inPumps; and Ido hereby declare that the following is a full, clear, andexact description of the same.

My invention, fully set forth hereinafter, is

an improved regulator for windmill-pumps. The general obj ect of theregulator is to throw the wheel of the engine out oi' the wind when thetanks are filled with Water.

The invention is illustrated in the accompanying drawings, in which-Figure l shows it in side elevation in connection with a section of thetank. Fig. 2 is an enlarged detail view of the lower portion of Fig. 1,some of the parts being in section; Fig. 3 is a View looking to the.left of Fig. 2, the parts being slightly raised from the stationaryseat. Fig. 4 is a plan View on the line cc .fr of Fig. 2. Fig. 5 is adetail view.

The pump-stock A is supported by a setscrew in a base plate B, restingupon the pump-platform in the ordinary manner. lTo the upper end of thisstock is iixed a castlng O, which supports the operating-lever and othermechanism hereinafter described, and is also provided with guides c c,in which the piston-rod extension works. The pump-stock A is tubular inform and its upper end is closed by the casting C. The lower end isthreaded into a chambered casting D, through which it has communicationwith the discharge-pipe and with the tank. The pistonrod is shown at E.lt passes through the central chamber ot' the casting D, being providedwith a packing e on the upper side and continuing through the mainforcing-pipe F to the suction and forcing cylinder below. The pipe F isscrewed into the castingD centrally thereof and forms direct connectionthrough the passages in the casting with the air-chamber in thepump-stock, the dischargepipe G, or the tank-pipe G', according to theposition of the valve in the left-hand chamber of the casting in Fig. l.Connected Withthe stock extension A is a branch pipe a, which isprovided with a piston or packing b on its lower end. Over this packingits snugly a cylinder H, which is screwed to the sliding head h, movingfreely on the pipe a,but forming a reasonably-tight joint. The head hhas ears Z, to which is hooked a bail f. The bail has an upper extensionin the form of a rod g, which in turn is connected with a chain le,attached to a wheel K. The pipe G opens into a tank L and is providedwith a valve o, adapted to remain open normally, but closed by a fioat mwhen the water is at the desired 6o height in the tank. When the wateris at the vdesired height in the tank, further operation of the pump,with the valve being set to turn the water into the tank through thetankpipe G', will force the water into the pipe A 65 and through thepipe a into the cylinder H, with the effect of forcing it downward,which will thus draw upon and turn the wheel K. The wheel K is on ashaft which has its bearings in the upper end of the casting C, on .7o

the opposite end of which shaft is a large wheel of the same kind,(marked K,) which has a short chain n attached to its periphery,provided with a weight which tends constantly to draw upon the yoke fand pull the cylinder up against the pressure of the water. Attached tothe same wheel K is achain or wire p, which extends to the Wind-wheeland is connected with it in the ordinary way, so as to pull the wheelout of the wind by the move- 8o ment of the cylinder H.

It will be understood that Ias soon as the valve in the tank is opened,admitting a discharge of water from the pipe G', the pressi ure will betaken off from the cylinder H,

and the weight will then turn back the wheel K to draw up the cylinder Hand slacken the wire chain, allowing the wheel to again turn into thewind. It will also be observed that the pump-stock A is arranged to actas 9o an air-chamber both in the ordinary operation of the pump and alsoin connection with the cylinder H. In the ordinary operation of the pumpthe water is forced up the pipe F and,

according to the position of the valve, into the action of air is alsoconstant through the pipe ct into the cylinder H, and this tends torelieve the cylinder H of any shock when the valve is closed, and theaction of the windengine is wholly against the cylinder.

The arrangement of the cylinder above described gives direct pull by thepressure of the water and simpliiies the construction as compared withthe arrangement heretofore used, in which a fixed cylinder is made tooperate upon a piston connected with the rod or chain, which operatesthe wheel to throw it out of the wind.

It will be observed that the pipe a is so adapted to the length andmovement of the cylinder H that when the said cylinder is drawn up toits upper limit its bottom bears against the lower end of the pipe, andthe packing of the end of the pipe is arranged to bear against thebottom of the cylinder when it is thus drawn up. This closes the end ofthe pipe and preventsieakage while the pump is working. The bottom ofthe cylinder may he formed with a plain iron seat, and the end andhaving a lower open end, and a cylinder sliding on said pipe, withoperating connections between said cylinder and the windmill,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

PHILIP A. MYERS,
